Author Information

  1. Emeritus Professor of Computational Structural Analysis, Cranfield University, UK

  1. This chapter draws very heavily on notes written by John Barlow for a lecture on finite element analysis at Cranfield University. At the time when the notes were prepared John was a structural analyst at Rolls Royce PLC at Derby, undertaking finite element analyses on aircraft gas turbine engines. He was also a founder member of the NAFEMS organisation set up to promote the safe and effective use of the Finite Element Method in industry.
